Hi Ron, et al..

Was there any further analysis of the spheroids that Opportunity had
encountered?, or have I missed something. I guess what I am asking is,
will it be possible to get a chemical composition of those spheres.
Thanks =20

SPIRIT UPDATE: Mega Drive - sol 43, Feb 16, 2004

Spirit spent the wee morning hours of sol 43 gathering data about a=20
wheel-track target with the M=F6ssbauer spectrometer, then tucked its =
arm=20
and drove. It used a two-session method engineers call a "mega drive" in

order to make good progress toward the crater nicknamed "Bonneville."
The=20
first driving session covered 19 meters (62.3 feet) after long-running=20
morning activities shortened the time for driving. After a rest, Spirit=20
continued another 8.5 meters (27.9 feet) in the afternoon, resulting in
a=20
total drive of 27.5 meters (90.2 feet), a new one-sol record. Sol 43
ended=20
at 9:58 a.m. Monday, PST. The remaining distance to "Bonneville" is
about=20
245 meters (about 800 feet) from Spirit's new location.

For sol 44, which will end at 10:38 a.m. Tuesday, PST, controllers plan=20
"touch-and-go" activities: deploying the arm on a target called "Ramp
Flats"=20
before continuing toward Bonneville.=20

OPPORTUNITY UPDATE: Check Before Digging - sol 22, Feb 16, 2004

Opportunity spent much of sol 22, which ended at 9:39 p.m. Sunday, PST,=20
making a thorough "before" examination of the spot selected for digging
a=20
ditch the next sol.

Also, Opportunity completed upward-looking observations before, during
and=20
after Mars Global Surveyor flew overhead looking down. Opportunity and=20
Global Surveyor have similar infrared sensing instruments: the miniature

thermal emission spectrometer on the rover and the (full-size) thermal=20
emission spectrometer on the orbiter. Coordinated observations of
looking=20
up through the atmosphere with one while looking down through the
atmosphere=20
with the other were designed to provide a more complete atmospheric=20
profile than either could do alone.

Sol 22's wake-up music was "Invisible Touch" by Genesis. In preparation=20
for digging, Opportunity examined the trenching site with its
microscopic=20
imager, its M=F6ssbauer spectrometer and, overnight, its alpha particle=20
X-ray spectrometer.=20

The plan for sol 23, which will end at 10:19 p.m. Monday, PST, is to dig
a=20
trench with alternating forward and backward spinning of Opportunity's
right=20
front wheel in order to see what's below the surface. Inspections of the

resulting hole are planned for sol 24 and the morning of sol 25.
